Automatic compensation of thermal disturbances in machine tools

Günter Spur & Uwe Heisel
This study deals with a practical method of reducing the effects of thermal disturbances upon the accuracy of machine tools by controlled feed adjustment at the tool. The spatial displacement between the cutting tooI and the workpiece closely correlates with the temperature increase in the machine tool. The equation which describes the relation between the displacement and the temperature for a certain operating condition can be written as a linear combination of temperature values. One...
